the like and more particularly to those' which are provided with an angularly adjustable back-mnnber which may b under spring action tending to return same to raised or normal position. A chair of the character specified is shown and described in my prior application, Serial No. 116,977,

filed August 25, 1916, of which the present application is a division. I

The invention consists in certain novel features of construction, hereinafter fully described and specifically claimed, these features including a locking vdevice for the back-member of the type which includes a notched plate engageable by a bolt un der control of the occupant, the improved construction comprising a lever pivotally mounted outside a frame member in a vertical direction with a spring bolt connected to said lever, and the notched plate secured to the side of the back-member between the latter and the frame and adapted to be engaged by the spring bolt.

A. latch is provided adapted to engage the lever for rendering the spring bolt inoperative at will.

The back member is pivoted in the frame by" means of a cross-rod, which is located at the base of the back-member and inclosed by said member for substantially its entire length, the protruding ends of said rod being pivoted in fixed relationship to the frame in bearing plates detachably connected to the inside of said frame, and held in said bearing plates by cotter pins.

Referring to the accompanying drawingsz- Figure 1 is a sectional elevation showing a chair having the present improvements applied thereto;

Fig. 2 is a detail side elevation on an enlarged scale showing part of the back-member and the locking device for holding same in adjusted position.

Fi 3 is a vertical section of Fig. 2 on the line A B.

her I) as by eye bolt connections 0 In said drawings the chair is shown as comprising front and rear legs or uprights a and a respectively, arms a aback-member b and seat member 0, the latter being pivoted at its front end at c to a cross frame member a thisseat member being under the action of a spring 0 and coupled to the back mem- The back-member is shown as suitably upholstered, and it may be formed in any appropriate manner, this member being pivoted in the rear'uprights a by means of a rod 6 extending through the back member so as to be hidden from view. The protruding ends of said rod each rest in a slot in the upper end of a bearing-plate b? secured to the inside face of each of the uprights a .as by screws 6 and the rod is secured against accidentalremoval from said slots by means of cotter pins 6 The said protruding ends of the rod between the backmember and the bearing-plates are encircled by thick washers 0 secured to the backmember as by screws b and which serve to prevent the rod from working loose on the back-1nember and maintain it in position between the bearing-plates.

The lockingdevice for securing the backiember in desired position comprises a plate- 1 secured outside one of the rear-uprights a and a second plate 6Z1 secured to the inside thereof, each as by screws (Z These plates form bearings and guides for a spindle (Z having at its enda catch (Z under the action of a spring d and pivoted outside the chair to one end of a lever (Z fulcrumed at (Z in lugs (Z formed on the plate (Z, the opposite end of said lever being enlarged as at (Z for ready manipulation by the hand of the occupant. The spring (Z tends to force the catch (i into engagement with one of a number of notches 6 formed in a curved plate 6 secured to the side of the back-member, so that said back-member may be held in any position of adjustment corresponding to said notches and may be released by the occupant of the chair by pressing upon the end (Z of the lever d but for the purpose of allowing the back-member to have freedom of movement I provide a latch f pivoted to the plate (Z and adapted to engage and retain the lever in the depressed position mentioned whereby the catch cZ cannot engage the notches in the curved plate 6.

What I claim.

,said notched plate, .thereby holding the to secureby Letters Patent of the United tates is 1. A chair or -'c0ucl1,-comprising, in coinbination, a frame comprising front and rear uprights, one of the rear uprights being formed with a horizontal aperture. which opens through itsopposite side faces; aback mein'ber pivotally mounted,betweensaidrrear uprights andh-aving a notched plate secured to its outer side face directly opposite the ,innerend gofgsaid aperture ,a bearing plate secured to-tlie outer side face of the zafper- :tnred ,upright, and provided with an openregistering with theouter end ofthe said apertnre; aQ-lever -fulcrumed intermediate its ends on i the bearing plate; a bolt. slidably 1nounted in said ,apertureand projecting at iits inner ',end through the inner end of the aperture forfiengagement with :the notched plate the onterend of said bolt projecting through the opening insaid bearing plate and being pivotally connected to the adjafcent endof saidlever; and-a spring in said "aperture encircling; said bolt and tending to IfprceQ-it "inwardly therethrough to engage free eilid iof s aid deter ,away "from said bearing ate. 2; Atchair op,couch,..compri sing, in combi- .n ation,,a :(fraine icoinprising front and rear uprights, one of the rear uprights being {formed with a horizontal' aperture which [opensthrough itsfopposite side faces a. back goplel ef this.patent ,mayflbe obtained for five .cents each,
